Lexus RX330 Mass Air Flow Sensor

The Mass Air Flow Sensor (MAF) is used in Lexus RX330 models to measure the flow of air into the engine as required for proper functioning of the engine. This information is communicated to the PCM which in turn alters the fuel injectors so as to keep the proper air-fuel mixture. The MAF sensor may be either Vane Meter (VAF) and Hot Wire sensors or of any other type that employs quite differing principles to measure airflow. The VAF sensor works on the principle of a spring loaded vane and the Hot Wire sensor measures change in current through a heated wire to get the airflow, which is more accurate. However, both types can be affected by contaminants such as the fuel and air in the terms of stalling or incorrect air-fuel ratio. The maintenance of the Mass Air Flow Sensor of the Lexus RX330 is crucial in the proper functioning and enhanced performance of the car's engine.
